Lightroom Desktop: Unusable after April 2020 update

It sounds like you have a bad install going as I have seen no other reports of performance degradation. I would recommend performing a clean reinstall. 

• Close Lightroom
• Restart the computer
• Use the Adobe Creative Cloud App to uninstall Lightroom Desktop
• Restart the computer
• Install Lightroom Desktop via the Creative Cloud App without launching any other programs.
• Restart the computer
• Verify Internet Connection
• Launch Lightroom
• Wait 5 minutes

Is that a typo - the current version is 9.2.1

Thanks for the fast reply Rikk. I've completed a reinstall following your steps and it hasn't made much difference. It's running very slowly. There's a huge lag when I'm panning around a photo that I'm zoomed in on or if I use the brush or eraser tools it doesn't immediately show the result, there's a couple of seconds delay before the effect is shown. Sometimes it also doesn't recognise I'm not holding down the mouse button and so paints a huge line across the photo when I move over to the tools sidebar - which obviously isn't intended. The program also freezes occasionally and gives the 'not responding' message at the top of the screen.
The problems are all hallmarks of trying to the run the program on a machine not powerful enough for it, but as I said previously it's only a few months old and was working flawlessly before the update so I can't see how that's the problem? I don't if maybe a recent windows update has also affected it? (I'm not IT savvy enough to know how all that works).

Brian, Creative Cloud Desktop is telling me I have version 3.2.1? See the screenshot.



Thanks for your help.

A couple of things to try:

1. Does the behavior show the same lag when you disable the GPU in preferences?
2. Does resetting the preference file help?

• Close Lightroom.
• Hold down [Alt/Opt]+[Shift] while restarting Lightroom.
• Overwrite the Preferences when prompted by the dialog.
• Close Lightroom.
• Restart Lightroom.

Note: A Preference File will survive a Lightroom uninstall/reinstall. Sometimes weird behavior is corrected/cured by resetting the preferences.

What operating system are you running Steven, out of interest?

I am finding exactly the same issue - LR Classic was working fine until the update and is now virtually unusable, with or without the GPU.
I have a slightly older system (AMD 6350 6-core CPU, RAdeon R9 270 Graphics, 32Gb RAM, Windows 10), but it was working adequately until the 'unhancement'. Sometimes a later hotfix stabilises things, but no joy this time.

If resetting the preference file did not affect the issue. The next step is to perform a clean reinstall. 

• Close Lightroom
• Restart the computer
• Use the Adobe Creative Cloud App to uninstall Lightroom Desktop
• Restart the computer
• Install Lightroom Desktop via the Creative Cloud App without launching any other programs.
• Restart the computer
• Launch Lightroom
• Wait at least 5 minutes

I seem to have fixed the problems I was having. A combination of the fixes suggest by Rikk seem to do the trick. I still get a bit of slow down on the odd photo which tends to be when there's a lot of editing applied, i.e. several overlays which I'll put down to my machine not being the highest spec around (even though I had no issues before the update).
Disabling use of the graphics card was also key.

Thanks for all the help/suggestions.

Hi, I'm experiencing the same issue and I had to downgrade back to Lightroom 3.2  from the latest update of 3.2.1 in order to use it with performance issues. Please check if this is a bug, bc I have tried every suggestion on this forum and nothing had helped fix the issue. Thank You. 5/25/2020

Same issue here. 6-7 support requests later with Adobe and nothing has worked in fact it’s now useless to the point I’ve downloaded a trial of Capture One.

i have the same problem, the program opens but i can't do anything no photos no sync. nothing everything is "gray"
